SKF 6211-ZNR bearing

55x100x21

Order what l thought was a set of SKF bearings for my R100GS gearbox (was advertised as SKF) from a german company but have been sent a set of FAG bearings all look the same apart from the the bearing that sits behind the circlip groove on the output shaft (need to have one machined on mine) the old NTN bearing has 5 roller balls and the new FAG 6 smaller ones .
